Description

Technical Field

[0001] This invention belongs to the field of construction solid waste treatment technology, specifically relating to a mobile continuous feeding construction solid waste hopper and material handling device. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] During the construction, expansion, renovation, demolition, and decoration of buildings in urban and rural areas, especially during demolition and decoration, a large amount of construction solid waste is generated. The treatment of construction solid waste involves its relocation, leveling, site clearing, loading, and transportation. Currently, these tasks are mostly completed by construction machinery such as loaders, bulldozers, and excavators. The current practice is that excavators first need to excavate and collect the construction solid waste, while simultaneously leveling the site. When the quantity of construction solid waste is large, it can be directly loaded onto trucks; when the quantity is small, it needs to be collected and transported back and forth until a certain amount is reached before loading. The transport vehicles then transport the construction solid waste to designated construction solid waste treatment stations for processing.

[0004] During the process of moving, leveling, cleaning, loading, and transporting construction solid waste, loaders, bulldozers, and excavators often cause dust and dirt to fly around when operating on the construction site, especially during the loading of construction solid waste onto trucks and the feeding process at the construction solid waste treatment station.

[0005] Many mobile construction waste treatment stations and fixed-location construction waste treatment stations currently lack self-retrieving capabilities. They mainly rely on excavators and grab bucket feeders (or automatic grab bucket cranes) to grab materials from the site or unloading pit and transport them to the construction waste treatment station by a feeder. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a mobile continuous feeding hopper for construction solid waste and a material handling device. This device can directly collect materials at the construction solid waste site and directly transport the construction solid waste materials to a mobile construction solid waste treatment device, enabling a single mobile construction solid waste treatment station to complete the entire process of material collection, processing, and aggregate output.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a mobile continuous feeding hopper for construction solid waste, comprising a bucket, wherein the bucket includes a fixedly connected receiving hopper and a conveying hopper, and an openable and closable door structure is provided between the receiving hopper and the conveying hopper; the bucket is hingedly connected to a movable jacking frame and a fixed jacking frame, the movable jacking frame is provided with a telescopic structure, the telescopic structure includes a fixed inner sleeve, a telescopic sleeve and a fixed outer sleeve fitted on the outer side of the fixed inner sleeve, and a reciprocating mechanism is provided between the telescopic sleeve and the fixed outer sleeve to drive the telescopic sleeve to reciprocate, thereby realizing the extension and retraction of the movable jacking frame and thus driving the bucket to deflect.

[0008] As a further technical solution, there is a gap between the telescopic sleeve and the fixed outer sleeve, and the movable push frame is also provided with a telescopic safety mechanism. The telescopic safety mechanism includes two fixed plates that are respectively fixed to the fixed outer sleeve and the telescopic sleeve, and the two fixed plates are provided with connecting pieces.

[0009] As a further technical solution, the door opening and closing structure includes a door panel that can be opened and closed, and the door panel is arc-shaped.

[0010] As a further technical solution, the door opening and closing structure includes a door panel, which is fixedly connected to a rack and pinion, the rack and pinion meshing with a gear, the gear being connected to a power device, and guide wheels are provided on both sides of the door panel.

[0011] As a further technical solution, the movable pusher and the fixed pusher are arranged in parallel, and both the movable pusher and the fixed pusher are connected to the bucket through a ball joint assembly; the ball joint assembly includes a ball joint seat, which is fixed to the bucket, and the ball joint seat is connected to the ball joint head, and the ball joint seat is fixedly connected to the pressure cover, which presses and fixes the ball joint head.

[0012] As a further technical solution, the hopper is equipped with shovel blades and a grid is provided on the hopper, the grid having a mesh structure.

[0013] As a further technical solution, the back of the bucket is connected to the inclined support cylinder, the inclined support cylinder is fixedly installed on the bucket by a ball joint, the end of the inclined support cylinder is hinged to the movable push frame, and the back of the bucket is also connected to the lifting cylinder.

[0014] Secondly, the present invention also provides a mobile construction solid waste collection and transportation device, including the collection hopper described above.

[0015] As a further technical solution, a tracked walking mechanism is also included, with a frame installed on top of the tracked walking mechanism, a material hopper connected to the tracked walking mechanism and the frame, and a driver's cab installed on top of the frame.

[0016] As a further technical solution, the frame is connected to the plate chain feeder, the input end of the plate chain feeder is connected to the conveying hopper of the material hopper, the output end extends upward, and a transition hopper is provided between the conveying hopper and the plate chain feeder; the upper part of the plate chain feeder is connected to the frame through a variable amplitude mechanism; the frame is equipped with a hydraulic power system.

[0017] The beneficial effects of the present invention are as follows: The material hopper of this invention is equipped with a dedicated opening and closing door structure. Its movable jacking frame is equipped with a telescopic structure that allows the jacking frame to extend and retract, thereby enabling the hopper to turn (achieving side-pushing). When the door is closed, it functions as a conventional bulldozer blade, capable of both horizontal and side-pushing. When the hopper is open, construction waste (or sand and gravel), under the action of the power system, combines with the tracked walking mechanism and the chain conveyor to form a material feeding device. This device directly transports the material to a mobile construction waste treatment station for processing while simultaneously collecting it; that is, construction waste is directly collected by pushing. For large pieces of construction waste that cannot be collected by direct pushing, one end of the bucket can be lifted by the bucket lifting cylinder, and the material inside the bucket is discharged directly through the conveying hopper due to the tilting action. The material collection method is convenient and flexible. The material hopper can be combined with various machines; the combined machine can be used as a bulldozer or as a material collector for a mobile construction waste treatment station.

[0018] The material hopper of the present invention is equipped with a grid, which is specifically used for separating large concrete blocks.

[0019] The material hopper of this invention can be pushed straight or at an angle by opening and closing the door, making it more convenient to collect construction solid waste, organize the site, and pick up and transport construction solid waste, thus realizing the integration of material picking and transportation of construction solid waste treatment station.

[0020] The material feeding hopper of the present invention can be easily connected to an external material feeding hopper, which is the material inlet of the belt conveyor, thus realizing the connection between the material feeding hopper and the belt conveyor.

[0021] The material handling and conveying device of this invention integrates material handling and conveying, enabling simultaneous material handling and external conveying. It is an independent mobile construction solid waste material handling and conveying device, and can also serve as supporting equipment for mobile construction solid waste treatment stations. As part of a mobile construction solid waste treatment station, the material handling and conveying device realizes mechanical material handling and conveying, and can also independently complete material handling and conveying, directly transporting construction solid waste materials to large transport vehicles.

[0022] The material handling device of the present invention allows the discharge port of the plate chain feeder to be easily connected to external machinery (connected to a mobile construction solid waste treatment station or an external construction solid waste transport vehicle) via a variable amplitude mechanism.

[0029] Example 1:

[0030] In a typical embodiment of the present invention, such as Figure 1 As shown, a mobile continuous feeding hopper for construction solid waste is proposed, which consists of a movable push frame 1, a diagonal brace cylinder 2, a ball joint 3, a ball joint assembly 4, a bucket 5, a door opening and closing structure 6, a grid 7, a blade 8, a bucket lifting cylinder 9, and a fixed push frame 10.

[0031] The bucket 5 is the main component of the material handling hopper, and all the main components of the bucket 5 are made of wear-resistant materials. The bucket 5 consists of two parts: the material handling hopper 51 and the material conveying hopper 52. The material handling hopper 51 and the material conveying hopper 52 are fixedly installed at the front and rear, respectively. The material handling hopper 51 is located at the front of the bucket in the material handling direction, and the material conveying hopper 52 is located at the rear of the bucket in the material handling direction.

[0032] The main function of the material hopper 51 is to collect materials, while the function of the material conveying hopper 52 is to transfer the material collected by the material hopper to the conveying machinery, such as the belt conveyor, so as to achieve the effect of collecting materials and conveying them out at the same time.

[0033] The hopper 51 includes a bottom plate 512, side plates 513, a curved panel 514, and a rear stiffening plate 516. The bottom plate 512 is located at the bottom. Side plates 513 are fixedly installed on both sides of the bottom plate 512. The curved panel 514 is installed between the side plates 513. A reinforcing plate 515 is fixedly installed on the back of the curved panel 514. The rear stiffening plate 516 is also fixedly installed on the side plates 513. The rear stiffening plate 516 is connected to a part of the side plate 513 on the side and connected to the curved panel 514 on the front. Together, they reinforce the side plates 513 and the curved panel 514. An upper crossbeam 517 is fixedly installed on the top of the side plates 513.

[0034] The material collection hopper consists of a bottom plate 512, a side plate 513, etc., forming a construction solid waste channel. The construction solid waste channel can be set as an inclined channel or an arc-shaped channel, which is conducive to the transportation of construction solid waste.

[0035] The conveying hopper 51 includes a bottom plate 521 and side plates 522. The bottom plate 521 is located at the bottom, and the side plates 522 are fixedly installed on both sides of the bottom plate 521. The bottom plate 521 is fixedly connected to the bottom plate 512 of the receiving hopper, and the bottom plates of the conveying hopper and the receiving hopper are on the same plane.

[0036] The blades, bottom plate, side plates, and grating of the bucket are all made of wear-resistant materials to ensure the bucket's wear resistance and service life.

[0037] The curved panel 514 is arc-shaped and is vertically arranged between the two hopper side plates 513. The bottom of the curved panel 514 is provided with a door opening and closing structure 6, which is located between the two hopper side plates 522.

[0038] The opening and closing door structure 6 consists of an opening and closing cylinder 62, a door panel 63, an ear plate 61, a connecting ear plate 64, a pin 65, bolts and nuts, etc. One end of the opening and closing cylinder 62 is connected to the door panel 63, and the other end is connected to the ear plate 61. The ear plate 61 is fixed to the upper crossbeam 517. The door panel 63 is located between the side plates 513 of the feeding hopper, and the door panel 63 can be opened and closed. In the closed state, the bottom of the door panel 63 is in contact with the bottom plate 512 of the feeding hopper. In the open state, the bottom of the door panel 63 is not in contact with the bottom plate 512 of the feeding hopper. The material enters the rear conveying hopper 52 through the gap between the bottom of the door panel 63 and the bottom plate 512 of the feeding hopper.

[0039] The switching cylinder 62 is connected to the door panel 63 via a connecting lug 64. The top of the door panel 63 is connected to the side plate 522 of the conveyor hopper via a pin 65, allowing it to rotate along the pin 65. The door panel 63 is arc-shaped and is opened and closed by the switching cylinder 62.

[0040] The door structure 6 has two states: open and closed. When the door panel 63 is closed, the bucket is mainly used to collect construction waste and level the site, similar to a bulldozer blade, capable of both horizontal and side-push. When the door panel 63 is open, for flowable construction waste and aggregates, the bucket can be used at the material collection point (e.g., ...). Figure 6 In the horizontal pushing state, construction solid waste or sand and gravel aggregate can be discharged from the hopper 51 along the arrow ( Figure 2 and Figure 3 The waste enters the conveying hopper 52 in the direction of the arrow; for construction solid waste with poor flowability, the machine uses the lifting cylinder 9 on the bucket 5 to lift the bucket 5. As the bucket 5 is lifted, the gravity of the construction solid waste generates a downward sliding force on the bucket 5, thus entering the conveying hopper 52 in the direction of the arrow, and finally entering the external conveying hopper, where the belt conveyor transports the construction solid waste to the mobile construction solid waste treatment station for processing.

[0041] The hopper 51 is equipped with a scraper blade 8 for material collection. The scraper blade 8 is made of a special wear-resistant material and is fixed to the hopper bottom plate 512 of the hopper 51 by fixing bolts 511. The scraper blade and the hopper bottom plate are arranged parallel to each other.

[0042] The hopper 51 is equipped with a grid 7 (see Figure 9a and Figure 9b The grating 7 has a mesh structure, and its shape is set according to the shape of the hopper. The main function of the grating 7 is to separate large pieces of construction solid waste, directly blocking them outside the bucket. The grating 7 is mainly welded from wear-resistant round steel.

[0043] The bucket 5 is connected to the back of the inclined support cylinder 2, which is fixedly mounted on the bucket 5 via a ball joint 3. The inclined support cylinder 2 controls the forward and backward tilting of the bucket 5. The end of the inclined support cylinder 2 is hinged to the movable push frame 1.

[0044] The back of the bucket 5 is also connected to the lifting cylinder 9. One end of the lifting cylinder 9 is mounted on the bucket 5 via a ball joint, and the other end of the lifting cylinder 9 is fixed to the frame (e.g., Figure 6 (As shown).

[0045] The supporting structure of the bucket consists of a movable pusher 1 and a fixed pusher 10, and the two pushers directly control the position of the bucket 5.

[0046] The movable pusher 1 and the fixed pusher 10 are arranged in parallel. One end of both the movable pusher 1 and the fixed pusher 10 is fixed to the shaft of the track by bearings. Under the action of the bucket lifting cylinder 9, they can rotate around the shaft of the track and be raised upward.

[0047] Both the movable pusher frame 1 and the fixed pusher frame 10 are connected to the bucket 5 via a ball joint assembly 4, such as Figure 10 As shown, the ball joint assembly 4 includes a ball joint seat 41, which is fixed to the bucket 5. The ball joint seat 41 is connected to the ball joint head 44, and the ball joint seat 41 is fixedly connected to the pressure cover 42 by a fixing bolt 43. The pressure cover 42 presses down and fixes the ball joint head 44, fixing its position so that it will not come out of the connection with the ball joint seat 41.

[0048] The function of the ball joint assembly 4 is to withstand the jacking force, transmit force and motion in multiple directions, and allow the connected components to rotate relative to each other in multiple planes (angular displacement) while preventing the components from being subjected to excessive bending moment.

[0049] Both the movable and fixed jacking frames are rod-type structures. The fixed jacking frame is permanently installed and cannot be extended or retracted; the movable jacking frame 1 is as follows: Figure 7 As shown, a telescopic structure is arranged, which is operated by a hydraulic cylinder 18 to realize the telescopic movement of the movable push frame 1. The telescopic structure includes a fixed outer sleeve 12, a fixed inner sleeve 13, and a telescopic sleeve 15. Both the telescopic sleeve 15 and the fixed outer sleeve 12 are fitted onto the fixed inner sleeve 13, with a gap between them. A reciprocating mechanism is provided between the telescopic sleeve 15 and the fixed outer sleeve 12 to drive the telescopic sleeve 15 to move back and forth. The reciprocating mechanism includes a hydraulic cylinder 18, one end of which is connected to a fixed ear plate 17, and the other end is connected to a fixed ear plate 19. The fixed ear plate 17 is fixed to the outside of the telescopic sleeve 15, and the fixed ear plate 19 is fixed to the outside of the fixed outer sleeve 12.

[0050] The movable jacking frame 1 is also equipped with a telescopic safety mechanism, such as... Figure 7 As shown, a fixing plate 16 is installed on the fixing sleeve 12 and the telescopic sleeve 15. A bolt 14 passes between the two fixing plates. The end of the bolt 14 is fixed by a nut 11. The length of the bolt directly controls the elongation of the telescopic sleeve 15, thereby playing a mechanical safety role.

[0051] When the total length of the movable pusher 1 is equal to that of the fixed pusher 10, the bucket is in the forward pushing state. When the hydraulic cylinder 18 extends or retracts, the telescopic sleeve 15 can move along the outer surface of the fixed inner sleeve 13, causing the length of the movable pusher 1 to change, thereby driving the bucket to rotate. Figure 8a , Figure 8b This causes the bucket to deflect, thereby pushing the construction waste to the side.

[0052] This material hopper works in conjunction with other machinery to achieve continuous feeding of construction solid waste. Continuous feeding refers to a device that can continuously and uniformly grab materials from raw material stockpiles (such as construction solid waste sites, construction solid waste pre-storage warehouses, or pre-stockpiles) and stably transport them to subsequent processing equipment (such as construction solid waste treatment plants).

[0053] Example 2:

[0054] In another embodiment of the present invention, a mobile construction solid waste collection and transportation device is provided, such as... Figure 11 As shown, it consists of a material hopper 21, a crawler walking mechanism 22, a frame 23, a plate chain feeder 24, a luffing mechanism 25, a driver's cab 26, a hydraulic power system 27, a connecting shaft 28, and a transition hopper 29. The material hopper 21 is the same as the material hopper in Embodiment 1.

[0055] The tracked walking mechanism 22 is located at the bottom, and the material hopper 21 is connected to the tracked walking mechanism and the frame, as described in Embodiment 1. The frame 23 is located on top of the tracked walking mechanism 22, and the driver's cab 26 is located on the top of the frame 23. The upper part of the plate chain feeder 24 is connected to the frame 23 through the luffing mechanism 25. The input end of the plate chain feeder 24 is connected to the conveying hopper of the material hopper 21, and the output end extends upward.

[0056] Because of its tracked walking mechanism, the material handling device boasts excellent maneuverability and off-road capability, making it more suitable for construction in solid waste sites. The device can travel straight, make gentle turns, and turn on the spot (i.e., make a U-turn), adapting to construction in narrow areas.

[0057] The frame 23 is equipped with a hydraulic power system 27, which powers the entire material handling device. The device is driven by a tracked walking mechanism 22, enabling it to move forward, backward, and turn. Simultaneously, the material handling device picks up material from the hopper 1 and, through the opening and closing gate structure 6 of the hopper 1, transports the construction waste to the chain feeder 4. The chain feeder 4 then transports the construction waste to a mobile construction waste treatment station or directly to construction waste transport vehicles. The material handling device can serve as an auxiliary device for mobile construction waste treatment stations, enabling material handling and transportation. Alternatively, it can function as an independent machine, directly picking up construction waste materials from construction waste sites and warehouses and transporting them to transport vehicles.

[0058] Sensors are installed in all key parts of the material handling device. For example, the plate chain feeder uses a cantilever beam load cell and a boom tilt angle sensor, the door panel position sensor of the opening and closing door structure, the position sensor of the movable push frame (i.e., the bucket status sensor), and the bucket lifting height sensor (which detects the angle between the movable push frame and the horizontal line). Each sensor feeds the system data back to the control box in the cab to realize the automatic control of the device.

[0059] The material hopper 51 picks up materials under the action of the hydraulic crawler walking mechanism 2, while the conveying hopper 52 transmits the material picked up by the material hopper to the plate chain feeder 4 through the conveying hopper, so as to realize the material is conveyed out through the plate chain feeder 4 at the same time as picking up the material.

[0060] In some embodiments, the door opening and closing structure 6 can adopt the form of the door opening and closing structure in Embodiment 1. In other embodiments, the door opening and closing structure 6 includes a rack 1087, a gear 1088, and a gear motor 1089. The three components are combined and directly fixed to the door panel 1085 with bolts 1086. The gear motor 1089 is connected to the gear 1088, the gear 1088 meshes with the rack 1087, and the rack 1087 is fixed to the door panel 1085. Guide wheels 1084 are provided on both sides of the door panel 1085. The guide wheels 1084 play a guiding role to ensure the direction of movement of the door panel 1085. Bearings 1083 are provided on both sides of the guide wheels 1084 and are connected by pins 1081 and sealing rings 1082.

[0061] A transition hopper 29 is provided between the feed hopper of the shovel and the plate chain feeder 24. The transition hopper transfers the material from the feed hopper to the plate chain feeder 24.

[0062] The door panel 1085 has two states: open and closed. When the door is closed, the bucket is mainly used to collect construction waste and level the site, similar to a bulldozer blade, capable of both horizontal and side-push. When the door panel 1085 is open, in the material-receiving position, for construction waste and aggregates with good flowability, in the horizontal-push state, the construction waste or aggregates can enter the conveying hopper from the receiving hopper along the direction of the arrow. For construction waste with poor flowability, the machine uses the lifting cylinder on the bucket to raise the bucket. Due to the raised bucket, the gravity of the construction waste generates a downward sliding force on the bucket, thus entering the conveying hopper along the direction of the arrow, and finally entering the transition hopper 9. The plate chain feeder 4 then transports the construction waste to the mobile construction waste treatment station for processing or directly to the construction waste transport vehicle. The door opening and closing structure is also equipped with a door panel position sensor to display the opening degree of the door panel 1085.

[0063] The plate chain feeder 24 comprises a driven sprocket 241, a guide wheel 242, a plate chain 243, an upper sealing cover 244, a drive sprocket 245, a drive motor 246, a discharge port 247, chain plates 248, and idler rollers 249. The output end of the plate chain feeder 24 has a discharge port 247. The drive motor 246 is connected to the drive sprocket 245. The chain plate 243 is fixedly mounted with chain plates 248 and is hooked onto the driven sprocket 241 and the drive sprocket 245. The chain plate 243 is also guided by the guide wheel 242. Idler rollers 249 are installed at the bottom of the chain, and an upper sealing cover 244 is installed on the side of the chain. The drive motor 246 drives the drive sprocket 245 to rotate via a transmission shaft, and drives the chain plates to move along the guide wheel 242 and idler rollers 249. Construction solid waste is fed into the feeding area of ​​the plate chain feeder 4 via the transition hopper 9, and moves obliquely upward under the drive of the conveyor chain until it is discharged from the discharge port 247 of the plate chain feeder 4. The plate chain feeder is equipped with a cantilever beam type load cell to detect the amount of construction solid waste conveyed, and also with a boom tilt angle sensor to display the angle of the tilting boom of the plate chain feeder, so as to control the height of the discharge port.

[0064] The plate chain feeder 4 is connected to the frame 23 via a connecting shaft 28. The connecting shaft 28 includes a rotating shaft 283, which passes through a Huff-type fixed flange 281. The Huff-type fixed flange is directly fixed to the frame 3 by bolts passing through bolt holes 282. When the plate chain feeder 24 is luffing under the action of the hydraulic cylinder 253 of the luffing mechanism 25, the plate chain feeder can only rotate around the connecting shaft 28.

[0065] To facilitate docking of the plate chain feeder 24 with the mobile construction solid waste treatment station, the mobile construction solid waste handling device is equipped with a luffing mechanism 25 for the plate chain feeder 24, used to adjust the height of the plate chain feeder. The luffing mechanism 25 is mainly used to adjust the luffing of the plate chain feeder 24 through a hydraulic cylinder 253. One end of the hydraulic cylinder 253 is connected to the frame 23, and the other end is connected to the upper side of the plate chain feeder 24 through a lug plate 251 and a pin 252. At the same time, a safety rope (not shown in the figure) is also provided between the plate chain feeder 24 and the frame 23 to ensure the safety of the plate chain feeder.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
